feat(backup): add backup.json for feature tracking and status updates

- Introduced a new `backup.json` file to track feature statuses, descriptions, and summaries for better project management.
- Updated `.automaker/feature_list.json` to reflect verified statuses for several features, ensuring accurate representation of progress.
- Enhanced `memory.md` with details on drag-and-drop functionality for features in `waiting_approval` status.
- Improved auto mode service to allow running tasks to complete when auto mode is stopped, enhancing user experience.
